Application filed April 8, 1913. Serial No. 759,715.

To all whom it may concern:

Be it known that I, GIOVANNI SAPEGNO, subject of the King of Italy,residing at Portici XX Settembre 29, Genoa, Italy, have invented new anduseful Improvements in Railway-Ties, of which the following is aspecification.

The object of the present invention is an improved, reinforced-concretetie or sleeper.

According to the present invention the improved tie consists of alattice beam of uniform resistance, expanded at its ends so as tofurnish large supporting surfaces for the rails. Said supportingsurfaces are so shaped as to provide a connection between the sleepersand the rails, their sole plates or chairs which is resilient to acertain extent, said connection being designed so as to allow the railsto be readily removed and also to be displaced so as to admit of thevariations of gage depending upon the superelevation of the outer rail,of'the change of some parts of the permanent way, and so on.

The accompanying drawings show, by way of example only, some of theconstructional forms of the improved tie.

Figure 1 is a side elevation partly in section. Fig. 2 a plan view,partly in section. Fig. 3 is a section on an enlarged scale on line X-X,Fig. 1. Figs. 4 and 5 are, respectively, an elevation partly in section,and a plan view partly in section of a modification. Fig. 6 is anenlarged section on line X'-X, Figs. 4 and 7 Figs. 7 and 8 are,respectively, an elevation partly in section, and a plan view partly insection, of a further modification of the improved tie.

In all of said figures ais the latticebeam of reinforced concrete orcement, which in the case of Figs. 1 and 4 has a parabolic upper chord.

b are the enlarged ends thereof offering an extended base to the railwaytrack.

According to Fig. 1 the rail and its sole plate are laid upon lugs-c ofreinforced concrete while according to F igs.'4 and 7 they rest uponprojecting brackets dd on the upper ends of posts -e of reinforcedconcrete. Both the lugs and the brackets are so dimensioned as. toafiord them the highest degree of elasticity consistent with therequired resistance to V stresses. In both cases'ample recesses fareprovided underneath for screwing and unscrewing the nuts of the bolts9, thus allowing the rail and its sole-plate to be secured in place orreadily removed if required, the recesses extending at their endsthrough the opposite side faces of the tie and being permanently openthroughout their entire extent. The holes provided in the aforesaid lugsor brackets admit of the position of the bolts being varied to a certainextent.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is:

1. A railway tie embodying a lattice beam of reinforced concreteprovided with rail-supporting surfaces and with a connecting portiontherebetween, said beam having a uniform cross-sectional resistancethroughout.

2. A reinforced concrete tie having its ends enlarged and formed withtransverse recesses, said recesses extending through the opposite sidefaces of the tie, the recesses being permanently open throughout theirentire extent.

3. A railway tie embodying a lattice beam of reinforced concrete havingenlarged, resilient end portions, said beam having a uniformcross-sectional resistance throughout.

4. A reinforced concrete tie provided at its ends with integral,projecting horizontal lugs to form supporting surfaces for the rails,said tie having transverse recesses beneath said lugs which extendthrough the opposite side faces of the tie and are permanently openthroughout their entire extent, said recesses affording access to thefastening bolts and nuts.

5. A reinforced concrete tie provided at its ends with integral,vertical posts having integral horizontal brackets on the upper endsthereof to form supporting surfaces for the rails, said tie havingtransverse recesses beneath said brackets which extend through theopposite side faces of the tie and are permanently open throughout theirentire extent, said recesses afiording' access to the fastening boltsand nuts.

6. A reinforced concrete tie provided at its ends with integral,horizontal supporting surfaces for the rails, said tie having transverserecesses beneath said surfaces which extend through the opposite sidefaces of the tie and are permanently open throughout their entireextent, said recesses afi ording access to the fastening bolts and nuts.
